I am a research scientist at Meta Reality Labs. Before that, I received my Doctorate from University of California, San Diego, advised by Prof. Manmohan Chandraker. My research interest is in 3D foundation models and feed-forward 3D reconstruction.
Internships at Meta: Please feel free to send me your CV and research interest to my personal email (lizhengqin2012-at-gmail-dot-com) or company email (zhl-at-meta-dot-com).
